IMPROVEMENT IN WASH-BOILERS.

Specification forming part of Letters Patent No. 174,776, dated March 14, 1876; application'led May 16,1874.

To all whom it may concern Be it known that I, DWIGHT BURDGE, of Brooklyn, in the county of Kings and State of NewYork, have invented certain Improvements in Wash-Boilers, of Which the following is a full, clear, and exact description, reference being had to the accompanying drawing, and the letters of reference marked thereon, making part of this specification, in which- Figure l is a side view of my improved wash-boiler. Fig. 2 is a longitudinal sectional view of the same.

My invention relatesto that class of Washboilers in which a rimless lid or cover is used,

and both the boiler and lid heilig so construct,

ed that-neither water nor soap-suds will be spilled, but be carried back into the boiler.

The nature of my invention consists in constructing the wash-boiler with a bead extending around the interior of t-he saine, said bead v forming a seat for the lid Aor cover, which is constructed without a rim, and provided with a valve and drain-tubes, for the purposes as hereinafter described.

The construction and operation of my invention are as follows: A is the wash-boiler, which may be constructed out of any suitable material, and in the usual manner, with one exception. At a certain distance from the top-of the wash-boiler I form a bead, B, which extends around the entire interior of the boiler and parallel with its top. The object of this bead is to provide a seat for the lid or cover E. Its advantages 'are that, being a portion of the boiler itself, and not connected therewith by any seamjont, there is no danger of the same becoming detached. And, again, it is less expensive than if solder was used for the purpose of attaching a separate strip of metal to the boiler to form the seat for the lid. This bead B is'formed on the boiler a distance sufficiently far below the top ot'ithe same that, when the lid E is put on and the Aboiler is in operation, a reservoir, C,

is provided to receive the water which has been forced above the lid by the action of the steam, and thus, in connection with the drainpipes D D, prevent the water or soap-suds from flowing over the sides of the boiler. E is the lid or cover, which is constructed without a rin]` and rests, when in position, on the bead B. D D are drain-pipes, which are attached to apertures cut in the lid E, and are tapering in form. Through these drain-pipes D D the waterand soap-suds which are. forced bythe steam into the reservoir O, through the connection formed by the lid and bead, are carried back into the boiler, and thus prevented froin overflowing vthe same. drain pipes D D are, preferably, located at the center of the lid, and on the incline ofthe same, a short distance from its edge. F is a valve which is so constructed that it may slide up and down freely on the wire F1. This valve F is, preferably, located immediately under the handle of the lid, and on a line With the drain-pipes D D. The Wire F1 is right-angularly bent, having one end fastened to the under side of the lid E, and just beyond the seat of the valve F, the other end being fastened to the handle F2 of the lid or cover. The object ot' this valve is to 'relieve the bottom ofthe drain-pipes D D from too great a pressure of steam, which would retard the flow ot` water from the reservoir back into the boiler.

What I claim as new, and desire to secure by Letters Patent of the United States, is-v The wash-boiler A, provided with a bead,B, in combination with the rimless lid E, provided with a valve, F, and drain-pipes D D, substantially as described. In testimony whereof I have signed my name to this specification in the presenc of two subscribing witnesses.
